Fly into Olbia in the north of Sardinia, and on the road to the Costa Smeralda it's easy to see why this stretch of coastline is reputed to be one of the most beautiful on earth. After a few days R&R at one of the excellent hotels, rent a boat for the day to explore the beautiful Maddalena Islands, or go diving on the wrecks of old Roman cargo ships. The hilly inland area is also worth exploration as it is particularly unspoilt.
Sardinia is renowned as a summer playground for adults indulging in a luxury holiday, and while undoubtedly being a destination that appeals to grown up kids, it's also pretty ideal for actual kids. There are miles of beautiful coastline to explore, you can hire a boat and visit the weird rock formations at Capo Testa or stop off to swim or snorkel in the famously translucent green waters to be found in dozens of secluded coves.
There are also other water sports on offer, particularly sailing and kite surfing, and terrestrial sports such as world class oligarch-spotting. This is best enjoyed of an evening in Porto Cervo checking out the none-too-subtle display of wealth as the mega-yachts jockey for position at the harbour.
